MACHINE FOR ORNAMENTING PAPER.

SPECIFICATION forming part of Letters Patent No. 410,155, datedSeptember 3, 1889. Application filed July 21, 1888. Serial No. 280,678.(No model.)

FREDERIO I-I. ROBIE, citizens of the United States, residing at Boston,in the county of Suffolk, State of Massachusetts, have invented certainnew and useful Improvements in Machines for Ornamenting Paper, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention has relation to mechanism for ornamenting paper, eitherin plain or ornamented straight, zigzag, or curved and parallel stripes.

'Among the objects of the invention are to provide a printing-roll whichcan be adapted for printing webs of paper of varying widths.

Other objects and advantages of the invention will hereinafter appear,and the novel features of the same will be particularly pointed out inthe claims.

Referring to the drawings, Figure 1 is a perspective of a machineembodying our invention. Fig. 2 is a diagram in side elevation, partlyin section; and Fig. 3, a detail in cross-section of a portion of theprinting-roll.

Like letters of-referen ce indicatelike parts in all the figures.

A represents a base or foundation, from which risers A A A project tosupport the operative parts of the machine. The risers A are preferablygrooved upon their upper edges for the reception of ribs B of theinkwell B, in order that said well may be moved upon the risers towardand away from the printing-roll of the machine.

Within the well B there is mounted for rotation an inking-roll 13*,which is preferably made of rubber, felt, or other elastic yielding andink taking or absorbing material.

0 represents the printing-roll of the machine, and its shaft 0 ismounted in bearings D, formed in the ends of rock-arms D,clamped to arock-shaft D mounted in the risers A the object of thus mounting theroll 0 being to permit of its being lifted upward and freed from theimpression-roll of the machine and over in rear of the ink-well, inorder that the length of the printing-roll, maybe varied ina mannerhereinafter described, and for other purposes. The printing-roll is madeup of a series of printing-wheels 0 preferably of metal which will notcorrode, although any desired material may be used in theirconstruction. Each of the wheels consists of a rim C the face orperiphery of which serves as a printing-surface, and as each wheel ofthe series is substantially an exact duplicate of the others the generaloutline of the rim may be varied laterally to produce impressions otherthan straight parallel stripes. So, also, may the surface orperiphery ofthe wheels be adapted to print ornamental designs. Each of --the wheelsis provided with a hub C of such dimensions that when several wheels areplaced upon the shaft C they will be properly spaced so as to printstripes at a uniform and desired distance from each other. Washers C maybe interposed between the wheels to widen the spaces between the stripeswhich they shall print.

As thus far described, it is apparent that in order to adapt theprinting-roll C for the ornamentation of webs of varying widths thenumber of wheels may be increased or decreased as circumstances mayrequire.

The impression-roll H is hollow and adapted to be supplied with steam inorder to quickly drythe ink upon the paper.

E represents a guide-roll.

Supported in any suitable manner, either as shown on the well B or uponthe base A, or otherwise, is a pneumatic ink-fountain F, having adischarge-pipe F, which is projected into the well to a point such adistance from the bottom thereof as will maintain a desired supply ofink therein.

F represents the supply-port of the fountain, and is adapted to beclosed bya plug F in order to render the fountain air-tight, so that theink will flow from the fountain to the well only when the supply in thewell is reduced so that the upper surface of the ink therein is belowthe lower end of the pipe F. In this manner a uniform quantity of ink ismaintained in the well, and therefore a uniform quantity is taken up bythe roll B and conducted to the printing-roll.

Certain features of construction are herein shown and described but notclaimed, as they form the subject-1natter of an independent application,Serial No. 280,67 6, filed herewith.

Having described the construction, the operation has therefore been madeapparent, it being substantially as follows: A web G of paper is passed,it may be as shown or in any other desired manner, between the printingand impression rolls, and the guide-roll E is arranged so as to hold theWeb in contact with the'combined drying and impression roll for agreater or less distance, in order that. the ink may be dried as soon asor immediately after it is applied to the web. From the guideroll theweb is conducted to any suitable mechanism for rewinding the same, or toanysuitable machine for manipulating the paper for any desired purpose.

To remove either the rolls C bodily, or any of thewheels' C from theshaft 0 a collar '0 on the shaft is first loosened, and then theclamp-coupling D of the arm D is loosened, so that said arm may be movedtoward the end of the shaft D thus removing the shaft 0 from thecoupling" D. Now, by removing the collar, wheels C may be removed "orreplaced upon the shaft C.

Having described ourinvention and its operation, what we claim is 1. Thecombination, with the printing-roll consisting of a shaft and a seriesof removable Wheels and means for holding said wheels to their shaft, ofrock-arms carrying bearings for said shaft, substantially as and for thepurpose specified.

2. The combination, with the impressionroll and the printing-rollconsisting of a shaft and a series of removable wheels on said shaft, ofthe shaft D parallel with the shaft of the printing roll, the rock armsdetachably clamped to said shaft D and provided at their ends withbearings in which the shaft of the printing-roll is journaled, and thecollar G 011 the shaft of the printing-roll, substantially as and forthe purpose specified.

5. In a machine of the class described,the combination of a flexibleelastic ink-supplying roll, a printing-roll having its printing-surfacevariable as to length, and a steam-heated drying' and impression roll,said printing-roll revolving' in contact with both said ink-supplyin gand impression rolls, substantially as described.
